Description

Technical Field

[0001] The utility model relates to a device for extracting eggs from living animals, belonging to the technical field of veterinary surgical instruments. Background Art

[0002] Live egg collection is a new type of livestock embryo engineering technology developed in the early 1980s. It uses a live egg collection instrument or some other simple devices to complete a series of processes of live oocyte collection. For example, the Chinese utility model patent with the authorization announcement number CN207590697U discloses an auxiliary device of an ultrasonic probe (i.e., an animal live egg collection device). The main body of the egg collection device includes a first frame, a second frame, and an intracavity probe (i.e., an ultrasonic probe). After the first frame and the second frame are matched, they are fixedly connected by hooks and slots. The shell of the ultrasonic probe is clamped in the cavity formed by the first frame and the second frame. The front end of the ultrasonic probe is exposed from the opening at the front end of the two brackets to scan the animal's intracavity tissue. In addition, semicircular guide grooves are integrally formed on the two frames to form a puncture channel for guiding the puncture needle after the two frames are fixed together; alternatively, no guide grooves are provided on the two frames, but the puncture channel is provided by an additional puncture guide accessory, which can be detachably mounted on the main body of the egg retrieval device when in use, thereby guiding the puncture needle to the egg retrieval site.

[0003] At present, the connection between the puncture guide accessory and the main body of the egg retrieval device is mostly a snap-on connection, which is similar to the connection between the first frame and the second frame in the main body of the egg retrieval device. Generally, a snap hook is set on the puncture guide accessory and a slot is set on the main body of the egg retrieval device to achieve the snap-on connection between the two. However, when installing and removing the puncture guide accessory, the snap hook needs to be deformed to a certain extent. After several times of disassembly and assembly, the snap hook is prone to fatigue, resulting in the inability to insert into the slot or the snap hook is directly broken and damaged. At this time, the puncture guide accessory needs to be replaced, which increases the maintenance cost. Utility Model Content

DETAILED DESCRIPTION

[0028] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0029] In response to the technical problems existing in the prior art, the basic technical concept of the utility model is to set a first magnet on one of the egg retrieval device main body and the puncture guide accessory, and set an adsorption structure that is adsorbed and matched with the first magnet on the other one, so that the egg retrieval device main body and the puncture guide accessory are detachably fixedly connected through the first magnet and the adsorption structure. Compared with the hook structure in the prior art, the adsorbed and matched first magnet and adsorption structure do not need to be deformed, have a longer service life, will not be scrapped due to several times of disassembly and assembly, and can reduce maintenance costs.

[0030] Embodiment 1 of the device for collecting eggs from living animals in the present utility model:

[0031] like Figure 1 As shown, the animal live egg retrieval device includes an egg retrieval device body 1 and a puncture guide accessory 2. Figure 2 , Figure 3 and Figure 6 As shown, the main body 1 of the egg retrieval device includes a first frame 11 and a second frame 12 that are fixed together. The two frames are fixedly connected by a hook and a slot structure, or fixedly connected by screws, which is convenient for manufacturing and assembly. After the two frames are fixed together, they include an operating part that extends in the front-to-back direction and is used to extend into the animal body for egg retrieval operations. The front end of the operating part is fixedly provided with an ultrasonic probe 14, and the ultrasonic probe 14 is used to scan the tissue in the animal cavity. The rear end of the operating part is a hand-held part, which is convenient for hand-held operation.

[0032] In the present invention, the puncture guide accessory 2 is installed on the upper part of the egg retrieval device body 1, such as Figure 6As shown, a first magnet 13 is provided on the egg retrieval device body 1, and an adsorption structure that is adsorbed and cooperated with the first magnet 13 is provided on the puncture guide accessory 2. The egg retrieval device body 1 and the puncture guide accessory 2 are detachably fixedly connected via the first magnet 13 and the adsorption structure. This method is not only convenient for disassembly and assembly, but also more durable. It will not be scrapped due to several times of disassembly and assembly, and the later maintenance cost is low.

[0033] Specifically, since the egg retrieval device body 1 is a two-half frame structure, a first groove for accommodating half of the first magnet 13 is provided on the first frame 11. Figure 7 As shown, a second groove 126 for accommodating the other half of the first magnet 13 is provided on the second frame 12, and both the first groove 126 are located at the rear end of the operating part. During installation, the first magnet 13 is first inserted into the groove of one of the frames, and then the other half of the frame is closed. After the two frames are fixed, the first magnet 13 can be limited to facilitate the installation of the first magnet 13. Of course, this installation method avoids the first magnet 13 being only provided on one of the frames, which causes the frame to be too large or the local volume to be too large. At the same time, this installation method also facilitates the disassembly between the two frames, and the first magnet 13 will not affect the disassembly.

[0034] In addition, the first groove and the second groove 126 both have a groove top wall, a groove bottom wall and a groove side wall, and the first groove and the second groove 126 only have relatively arranged grooves, and the wall thickness of the groove top wall satisfies that the first magnet 13 can be attracted to the adsorption structure on the puncture guide accessory 2, so that the first magnet 13 is completely limited in the two frames, realizing the embedded installation of the first magnet 13, avoiding the risk of the first magnet 13 still being detached when there is no groove top wall.

[0035] like Figure 8 As shown, the puncture guide accessory 2 includes a plastic main body 21 extending in the front-to-back direction and a metal head 22 fixed to the rear end of the plastic main body 21. The adsorption structure on the puncture guide accessory 2 is a second magnet 23. The second magnet 23 and the first magnet 13 are attracted to each other, and the adsorption force is stronger, which can ensure the fixing effect between the egg retrieval device body 1 and the puncture guide accessory 2. Further, as Fig. 9 As shown, the metal head 22 is provided with a fitting surface 222 that is in contact with the main body 1 of the egg retrieval device, and a mounting groove is provided on the fitting surface 222. The second magnet 23 is fixed in the mounting groove, and the magnetic surface of the second magnet 23 is flush with the fitting surface, so that the adsorption effect is better. In addition, the second magnet 23 is installed on the metal head 22 through a fixing screw 24. The metal head 22 is provided with a threaded hole that matches the fixing screw 24. The second magnet 23 is provided with a screw through hole for the fixing screw 24 to pass through and corresponding to the threaded hole. The screw through hole is a countersunk hole to prevent the head of the fixing screw 24 from protruding from the fitting surface 222 and affecting the adsorption and fixation.

[0036] As can be seen from the above, the first magnet 13 is located at the rear end of the operating part of the egg retrieval device body 1, and the second magnet 23 is located at the rear end of the puncture guide accessory 2. The operating part and the puncture guide accessory 2 have a certain length in the front-to-back direction. In order for the two to be stably fixed, a guide structure for guiding the puncture guide accessory 2 from the back to the front needs to be provided on the operating part. Figure 3 and Figure 4 As shown, a first protrusion 111 is protrudingly provided on the top surface of the first frame 11, a second protrusion 121 is protrudingly provided on the top surface of the second frame 12, a first guide rib 112 is provided on a side wall of the first protrusion 111 away from the second protrusion 121, and a second guide rib 122 is provided on a side wall of the second protrusion 121 away from the first protrusion 111, and both guide ribs are flush with the top surface of the corresponding protrusion, but are at a certain distance from the top surface of the corresponding frame.

[0037] like Fig. 9 and Fig.10 As shown, two guide grooves 212 are provided on the plastic main body 21. The two guide grooves 212 are symmetrically arranged and extend in the front-to-back direction. During installation, the notch at the front end of the guide groove 212 is aligned with the above-mentioned first guide rib 112, and the puncture guide accessory 2 is pushed forward. The first guide ribs 112 on both sides enter the guide groove 212 respectively, to guide the installation of the puncture guide accessory 2, and to prevent the puncture guide accessory 2 from moving left and right and falling out upward. After complete installation, the second magnet 23 moves to the position corresponding to the first magnet 13, and is fixed by the adsorption force of the two.

[0038] Further, if Figure 4 As shown, a first stop step 113 for limiting the forward installation limit position of the puncture guide accessory 2 is provided at the rear end of the first frame 11 corresponding to the operating part, and a second stop step 123 for limiting the forward installation limit position of the puncture guide accessory 2 is provided at the rear end of the second frame 12 corresponding to the operating part. After the two frames are matched and fixed, the first stop step 113 and the second stop step 123 are aligned to form a stop step for stopping the puncture guide accessory 2. Therefore, a matching step for matching with the stop step is provided at the rear end of the plastic main body 21 of the puncture guide accessory 2. Among them, the first frame 11 is also provided with a first adsorption surface 114 vertically connected to the first stop step 113, that is, the outer surface of the groove top wall of the above-mentioned first groove. The second frame 12 is provided with a second adsorption surface 124 vertically connected to the second stopping step 123, that is, the outer surface of the top wall of the second groove 126. After the two frames are matched and fixed, the first adsorption surface 114 and the second adsorption surface 124 are aligned for adsorption and bonding with the above-mentioned bonding surface 222.

[0039] In addition, Figure 5 As shown, a first stop end face 115 is provided at the front end of the first frame 11, and a second stop end face 125 is provided at the front end of the second frame 12. After the two frames are matched and fixed, the first stop end face 115 and the second stop end face 125 are aligned to cooperate with the front end face of the puncture guide accessory 2 to limit its forward installation limit position.

[0040] In the present invention, the metal head 22 and the plastic body 21 are respectively provided with guiding structures for guiding the puncture needle. Figure 2 , Fig. 9 and Fig.10 As shown, the guide structure on the metal head 22 is a guide circular hole 221, and the guide structure on the plastic body 21 is a second arc groove 211 with an opening facing downward and a semicircular cross section. Figure 4 As shown, a quarter arc groove is provided on the opposite side of the first protrusion 111 and the second protrusion 121. After the two frames are matched and fixed, the two quarter arc grooves are connected to form a first arc groove with an upward opening and a semicircular cross-section. When the puncture guide accessory 2 is installed on the egg retrieval device body 1, the first arc groove and the second arc groove together form a guide channel for guiding the puncture needle. Semicircular arc grooves are respectively provided on the puncture guide accessory 2 and the egg retrieval device body 1, and the two together form a guide channel to avoid the puncture guide accessory 2 being too large when all are provided on the puncture guide accessory 2, thereby causing the egg retrieval device to be too large, affecting the egg retrieval operation by entering the animal body.

[0041] In addition, if Figure 2 and Fig. 9 As shown, a tightening screw 25 is also installed on the metal head 22, and the end of the tightening screw 25 is used to extend into the guide circular hole 221 to tighten the inner liner installed in the guide channel. At this time, the diameter of the puncture needle is smaller than the inner diameter of the guide channel, and the puncture needle passes through the inner liner. Of course, if the diameter of the puncture needle is compatible with the guide channel, there is no need to use the inner liner and the tightening screw 25.

[0042] In other embodiments of the device for retrieval of living animal eggs: the guide channel can also be separately provided on the puncture guide accessory, and in this case, the main body of the egg retrieval device does not need to be provided with an arc groove.

[0043] In other embodiments of the device for retrieval of live eggs from animals: the puncture guide accessory can be stopped by only the stopping step on the main body of the egg retrieval device, and there is no need to set a stopping end surface at the front end of the first frame and the second frame; of course, in other embodiments, there is no need to set a stopping step on the first frame and the second frame, but the stopping end surface at the front end is used to stop the puncture guide accessory; in other embodiments, neither a stopping step nor a stopping end surface is set, and after the second magnet moves to the position of the first magnet, it can be naturally adsorbed and fixed.

[0044] In other embodiments of the device for retrieval of live eggs from animals: a guide structure may not be provided on the operating portion of the main body of the egg retrieval device, that is, no protrusions or guide ribs are provided on the two frames, and no guide grooves are provided on the puncture guide accessory. In this case, a first magnet may be provided at the front and rear ends of the operating portion, respectively, and correspondingly, a second magnet may be provided at the front and rear ends of the puncture guide accessory, respectively. When the puncture guide accessory is installed, it is directly aligned with the main body of the egg retrieval device and fixed by adsorption by the magnets at the front and rear ends.

[0045] In other embodiments of the device for retrieval of live animal eggs: the puncture guide accessories can be made entirely of plastic material, in which case the threaded holes are directly opened on the plastic material, or of course a metal insert can be embedded in the plastic material during injection molding, and the threaded holes are set on the metal insert. Of course, in other embodiments, the puncture guide accessories can also be made entirely of metal material.

[0046] In other embodiments of the device for retrieval of living animal eggs: the second magnet can also be bonded and fixed to the puncture guide accessory, and in this case, there is no need to set a threaded hole on the puncture guide accessory.

[0047] In other embodiments of the device for retrieval of live animal eggs, the magnetic attraction surface of the second magnet may also be located on the inner side of the fitting surface, and the two are not flush. Of course, in other embodiments, the second magnet may also be installed in an embedded manner, and like the first magnet, it is adsorbed through a thin wall.

[0048] In other embodiments of the animal live egg retrieval device: when the puncture guide accessory is entirely made of metal material, the adsorption structure on the puncture guide accessory does not need to be the second magnet, but a local metal surface of the puncture guide accessory; of course, in other embodiments, the main body of the puncture guide accessory can be made of plastic material, but a metal sheet or metal block is locally fixed, and the metal sheet or metal block is adsorbed and fixed with the first magnet.

[0049] In other embodiments of the device for extracting eggs from living animals: the first groove on the first frame can also have a top notch, and the second groove on the second frame also has a top notch. At this time, the first magnet does not need to be installed in a certain groove in advance, but after the first frame and the second frame are aligned and fixed, the grooves on both sides will form a complete groove with an open top. At this time, the first magnet can be placed in the complete groove, and the magnetic surface of the first magnet is exposed. In order to fix it, double-sided tape can be set on the groove wall of the complete groove to bond and fix the first magnet in the complete groove. This method also ensures that the two frames can be disassembled.

[0050] In other embodiments of the device for retrieval of live animal eggs: when the first magnet is arranged on the main body of the device for retrieval of eggs, the first groove can be arranged only on the first frame, or the second groove can be arranged only on the second frame. At this time, the first magnet is only installed in the first groove or the second groove, and the installation method can be embedded or the magnetic surface can be exposed.

[0051] In other embodiments of the device for retrieval of living animals, the first magnet can be disposed on the puncture guide accessory, and the adsorption structure is disposed on the main body of the egg retrieval device. The main body of the egg retrieval device can be made entirely of metal material, and the adsorption structure is a local metal surface of the main body of the egg retrieval device. Of course, in other embodiments, the main body of the egg retrieval device can be made of plastic material as a whole, and only a metal sheet or metal block is fixed locally, and the metal sheet or metal block is fixed by adsorption with the first magnet.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
